Can I easily bootload an nRF52832 using a BeagleBone Green Wireless and its built in bluetooth?

[Henry McDonald]

We have a handful of products that utilize nRF52832 IC's for BLE communication.  The bootloader in these devices is based on the one in the SDK, I believe version 11.0.  In any case, the bootloader works with nRF Connect on my Android phone.

We are preparing to ship a BeagleBone Green Wireless (BBGW) based device alongside the BLE devices.  I'm investigating how I can bootload the Nordic parts via BLE.  I am aware of nrfutil and have been able to get it running on the BBGW, but it appears to require a BLE dongle to work.  We're not going to be able to add a dongle to every BBGW we ship, so that isn't an option.

Is there a solution to bootload an nRF52832 using the BBGW's on board Bluetooth IC?

Hello,

Unfortunately, we do not have any offical examples that demonstrates OTA DFU with other Bluetooth stacks such as Bluez, but I found this github project that you might want to check out (not tried it myself): https://github.com/foldedtoad/ota-dfu-python.

Note that Nrfutil and nrf connect desktop use serialized softdevice API to control the softdevice on the connectivity board (serialization). This is why you need a nordic dongle when doing OTA DFU with nrfutil.
